British scientists have developed a zwitterionic ligand salicyclaldoxime that can allow an industrial ion - metal ions from other substances important for selectively updated. Some molecules that bind both ions - metal salt ions independently, where it should be improved efficiency of the extraction process. Approximately 25 percent of copper in the world is updated by using phenolic oxime extractant conventional, which only binds copper cations, not the spouse of the anion.

When several extractant to transfer copper from an aqueous solution into the organic phase, there is a build up of acid in the aqueous phase, which then must be neutralized, completed the extraction process. This technology could eventually find applications in the improvement of commercial varieties of base metal.

Tasker dialkylaminomethyl and his colleagues made a substitute salicyclaldoximes capable of binding a metal cation and the accompanying anions in a separate location from the zwitterionic form of the extractant with a neutral charge assemblies. Tasker explained that 'the new reagent extracts the metal salt, which is contrary to conventional oxime reagent that transports metal cations' and as a result there is no net exchange of cations or anions, which makes them well adapted to overcome the waste stream. As a consequence of the structure formed by the bus trans-salicyclaldoximato complex of Cu (II) complex is tritopic which means that the divalent metal can be moved with their two mono-anions simultaneously, leading to further increases in efficiency.

Trans structure formed by bis-salicyclaldoximato complex of Cu (II) has three bonding sites, the core principle of the science of supramolecular chemistry has been used to solve a very important industrial problems, one of the biggest challenges associated with commercial exploitation of the new reagent is getting high selection of both cation and anion delivery. This work has shown that cooperative binding of the cation and anion will resolve this matter.
